Filed: 1935-07-27
Abstract: 460,443. Sewing - machines. UNION SPECIAL MACHINE CO. July 27, 1935, No. 21343. Convention date, Jan. 15. [Class 112] A sewing-machine with a four-motion feed dog mechanism as described in Specification 413,120 has manual means for readily varying the stitch direction and stitch length. The variable setting means 36, 34 for the stitch length is as described in Specification 413,120. The stitch length and direction is varied by turning the crank handle 45. This rotates the shaft 42 to cause arms 41, 40, 38 to rock the shaft 37 and so alter the feed rocking motion of the feed bar 10 on the feed rock shaft 23. The shaft 42 is carried through the casing 3 and has a pointed member 46 fixed thereto. This member co-operates with a flat spring 48 and adjustable screw stops 53, 54. As the pointed member is moved between the stops, it varies the feed and length of stitch. As the pointer snaps across the flat spring to the extreme position or the other, it varies the direction of feed.

Abstract: 356,387. Spirit levels. POWELL, A. D., 31, Clare Road, and BRADBURY & SONS, Ltd., J., New Street Works, both in Braintree, Essex. July 17, 1930, No. 21627. [Class 97 (ii).] An alignment gauge for the wheels and axles of automobiles comprises a beam provided with two arms the extremities of which are finished with blade-shaped contacting points to engage the wheel the angular relation of which to the vertical is indicated by a rotatable spirit level indicating on a graduated arc. The beam A is provided with arms B which may be adjustably clamped along the length of the beam each arm being provided with blade contacts C secured by set screws B<1>. The beam carries two fixed spirit levels for indicating the horizontal and vertical and a level A3 pivoted at A<1>. The Figure shows the gauge applied to the outer surface of the wheel to indicate its outward tilt. The car is first levelled by adjusting the arms B so that the contacts C engage the underside of the springs at the point of attachment to the front axle and using the level A<1>. Then the arms are brought against the wheel rim as shown in the Figure with one end of the rod touching the ground the beam being positioned vertically by using level A<2> and the blades C aligning with the beam. The tilt of the level A<3> gives the angle required. For testing the front axle when removed, it is held in a vice and the spring platforms adjusted to the horizontal by using the beam A with the arms removed as an ordinary level, or if this is impossible, the arms are replaced and adjusted to engage the platforms. Mandrels are then inserted in the pivot holes of the stub axle pivot pins and the blades C adjusted to engage the mandrel by their notches C<1>. The rotary level A<3> gives the inclination of the holes. The tool is then moved through 90‹ and the angle in the opposite direction taken.

Abstract: 577,114. Heatexchangers. ROBERTSON, J. H. Dec. 28, 1943, No. 21716. [Class 64 (iii)] In a heat exchange apparatus, e.g., for cooling oil or abstracting heat from the induction mixture of an aircraft engine, in which the matrix is composed of tubes arranged in cellular groups or bundles through and between which the fluids flow, each group or bundle comprising primary surfaces swept on opposite sides by the two fluids and secondary surfaces swept on both sides by the same fluid, each cellular group or bundle comprises at least two rows of two or more separate individual tubes a assembled as parallel elements, with primary surfaces formed by the exposed walls b of the outer tubes and imperforate secondary surfaces c each formed by two tube walls in metallic contact with one another. The tubes may be of square, hexagonal or other polygonal crosssection. An oil-cooler, Fig. 2, is' composed of groups of tubes A, B, C arranged within inner and outer cylindrical casings e, f. The oil passages between the groups of tubes are closed at the front and rear by a wire grid or pressed metal grille, and between the front and rear there may be similar grids or grilles, together with annular partitions between the outer groups of tubes and inner casing e, to form baffles. The annular partitions contain apertures j<1> for the passage of oil. The width of the vertical passages between the groups of tubes is proportionate to the length of the vertical chord through it, to keep the resistance to the flow the same in all paths. Strips k prevent oil from by-passing the passages between groups of tubes. The space between the casings e, f forms a by-pass through which oil flows when a relief valve opens under excessive oil pressure. The outer casing f is stiffened by annular ribs h of channel cross-section. Specification 159,388, [Class 64 (iii)], is referred to. According to the Provisional Specification the primary or secondary surfaces or both may be indented or corrugated.

Filed: 1974-05-17
Abstract: 1436668 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 17 May 1974 [29 June 1973] 22197/74 Heading B6F A printer has a type head 16 mounted on a carriage movable in a letter spacing direction, and comprising a barrel cam 68 on the carriage having a plurality of cam tracks, which are selectively engaged by a selecting device, this engagement causing axial displacement of the cam 68 when it is rotated and this displacement is used to cause a type selecting movement of the type head 16.  Type selection.-A golf ball type head 16 is rotated by the selective engagement of one of the sliding racks on member 120 with pinion 128, the racks being moved by one of the followers 164, 166 engaging an end face of the barrel cam 68 as it moves axially along shaft 82. The tracks on the cam 68 produce varying axial displacements, each track being associated with a follower which is held out of engagement until its associated latch (32-41), Fig. 5 (not shown), is roleased by an electric or pneumatic signal from a keyboard. Only one follower engages the cam 68 at a time. Alternatively, Fig. 19- 26 (not shown), the barrel cam carries a single track with parallel loops of varying depth and a single follower is adjusted for its depth of penetration (corresponding to a particular loop of the track) by signals from the keyboard. The tilting of the head 16 is controlled by barrel cam 168 having tracks producing axial displacement of the cam 168 when engaged by a follower controlled from the keyboard. The displacement of cam 168 is followed by tab (186) of bellorank (188), Fig. 8 (not shown) which in turn rocks bellcrank arm 194 to move link 198 attached to the head 16.  Case shift.-This is achieved by disengaging an escapement mechanism used to advance the carriage and advancing one of the racks as far as possible in one direction and then changing over the racks, this effects a 180 degree change in the position of the head 16.

Title: Improvements relating to brakes
IPC: F16D65/58
Filed: 1946-07-26
Abstract: 614,756. Compensating for wear in brakes. PRATT, J. H., and MANLEY, G. E. July 26, 1946, No. 22235. [Class 103 (i)] In automatic wear-compensating devices of the type in which a stop member is carried by a brake shoe or other friction member and engages the surface to be braked so as to be adjusted relative to the shoe &c. against a frictional resistance as the lining wears, this stop member engaging a fixed abutment to determine the " off " position of the shoe etc.; the stop member 18, 182, Fig. 1, or 184, Fig. 3, has an inclined surface 183 or conical end 185 engaging the abutment 23 so that the thrust between the member and abutment is inclined to the axis of movement of the member and a high frictional resistance is created between the member and its mounting which prevents adjustment of the member by the means, such as a spring 27, for withdrawing the brake shoe &c. from the surface to be braked. The frictional resistance against which the member is adjusted by engagement with the surface may therefore be reduced to a value just sufficient to prevent relative movement of the member when it is out of engagement with the surface or abutment, and wear between the member and surface is thus avoided. In Fig. 1, the plate 18 forming part of the stop member has an elongated slot 181 embraced by friction washers on a bolt 17 passing through a hole in the shoe web, the washers being loaded by a spring interposed between the opposite side of the web and a nut on the bolt. The plate is secured to a feeler. 182 which is a sliding fit in a hole in the shoe flange 101 and extends through a clearance hole in the lining 102. In Fig. 3, the member 184 is slidable in a block 29 secured to the shoe web and is engaged frictionally by a spring 30. The abutments 23 are carried by eccentrics 24 which may be rotated in the backplate to adjust the clearance between the shoes and the drum. Specification 314,607, [Class 103 (i)], is referred to.

Abstract: 502,565. Coating welding-electrodes by extrusion. BABCOCK & WILCOX, Ltd. Aug. 16, 1937, No. 22421. Convention date, Nov. 3, 1936. [Class 87 (ii)] [Also in Group XXII] Weldrods are given a partial coating of flux by moving them longitudinally through a dio orifice supplied with the flux material and, during a portion of their travel, shielding the die orifice from the material so that a length of the weldrod is left uncoated. The weldrods C are stored in a hopper 5 whence they are fed by rolls 13 into a vertical shoot 12, from which they are pushed, one at a time, by a plunger 15 which carries a cam member 18 engaging a rod 19 to operate the rolls 13 by a ratchet device 20. The rods are then fed by rolls 7, 8, one of which is resiliently mounted, into the bore 35 of a guide 31 which supports the rod during its passage through the die 52. The coating material is supplied to the die by a plunger 10 and the guide 31 is periodically reciprocated so as to contact with the die 52 and cut off the supply of material to the weldrod. The guide 31 is normally maintained in its retracted position by springs 59. The rolls 7, 8 are driven from a motor 36 and carry a crank pin 24 which actuates the plunger 15 and a cam 25 which reciprocates the guide 31 through a lever 27. The ram 10 is operated by motors 84 through a screw 80 and its movement is controlled by.a limit switch 94. The weldrods may have one or more bare portions and may be circular in cross-section. Alternatively they may have projections 67, Fig. 9, which project beyond the coating 68. Specification 424,960, [Group XXII], is referred to.

Title: Improvements in or relating to presses suitable for use in performing cutting operations on sheet material
IPC: A43D8/04
Filed: 1965-05-27
Abstract: 1,110,595. Cutting-out presses. BRITISH UNITED SHOE MACHINERY CO. 27 May, 1965 [28 May, 1964], No. 22503/65. Heading B4B. In a cutting press comprising a bed 10, Fig. 1, having an electrically conductive pad 12, supporting a workpiece 14 of sheet material on which a knife 16 is placed, a beam 18 having an electrically conductive striking- plate 20, fluid-pressure control means for moving the beam towards and away from the bed and thereby urging the knife through the workpiece to contact the pad, the control means including an hydraulic piston and cylinder 24 supplied with fluid from a sump 28 by means of a pump P driven by a three-phase electric motor M which also drives a flywheel F, the pump supplying fluid through a solenoid valve having a spool 30 and a winding S energizable to cause the spool, and thereby the beam, to be moved downwardly, the control circuit of the press is arranged so that in response to slowing of the pump to a predetermined speed, the motor M is decelerated thereby de-energising the winding S to terminate the downward movement of the beam and cause the beam to return to its upper position. The control circuit comprises a transformer 60, Fig. 2, having a primary winding 62 and secondary windings 64, 66 and 68. When a handle 40, Fig. 1, on the beam is moved downwardly to move the armature 44 of a switch 42 from a contact 46 to a contact 48, the circuit containing leads 70, 72 is tripped to lock transistors 90, 100 to energize the winding S. The circuit is unlocked by means of a limit switch LS or by applying the voltage across a resistor 182 of a beam contact sensing circuit 150 across a resistor 112 to cut off transistor 100. This permits a bias supply containing secondary winding 66 to apply turn off reverse bias to transistor 90 thus de-energizing winding S. The circuit 150 for bringing about an automatic reversal of the beam on the completion of a cutting operation comprises two stages of amplification, including transistors 160, 180, and one stage, including transistor 190, providing a variable time delay. To indicate the presence of current above predetermined value in one of the leads of the motor M corresponding to slowing of the pump, the primary winding of a transformer 200 is connected with a lead 202 of the motor M, a secondary winding 204 of the transformer being connected in a circuit extending between the base of transistor 100 and lead 72 through a neon tube 206, a diode 208 and the primary winding. The diode is poled so that a negative voltage only is applied to the tube 206 which when it exceeds the breakdown voltage of the tube, is applied to the base of transistor 100 to turn it off. This causes transistor 90 to be turned off thereby deenergizing winding S.
